Amplification of the Electroosmotic Flow on Superhydrophobic Surfaces (C05)

电渗透流（EOF）可以使流体沿着表面或通道泵送，并在微流体和芯片实验室技术中得到应用。理论结果表明，与光滑表面相比，当采用特定的电极结构和超疏水表面时，这种流动可以提高两个数量级以上。这将使一系列全新的应用成为可能。利用其他子项目的见解及其润湿特性，该项目打算通过实验研究这些EOF配置对流动的增强作用，然后解决优化设计问题。

Electroosmotic Flow (EOF) enables fluids to be pumped along a surface or in a channel and finds applications in microfluidics and lab-on-a-chip technology. Theoretical results indicate that this flow can be enhanced by more than two orders of magnitude when specific configurations of the electrodes and superhydrophobic surfaces are employed, compared to smooth surfaces. This would enable a whole new spectrum of applications. Using the insights from other subprojects and their wetting characterization, the project intends to experimentally investigate the flow enhancement using these EOF configurations, and then to address the question of optimal design.
